I just bought a 210 and was trying it out using mythtv. While watching a recording within 5 minutes the computer becomes non-responsive, I get a blank screen on the lcd tv with the hdmi 3 showing. This happened 3 times in a row. I was using 260.19.26 and I upgraded to 260.19.29 and got the same result. I was previously using a 9600GT with the 260.19.26 driver without an issue. The TV is connected via HDMI / DVI cable to the video card. I bought the card off Newegg:
